The Chicago Cubs and Philadelphia Phillies have been in trade talks since the Cubs claimed Phillies left-handed pitcher Cole Hamels off waivers Wednesday, but a deal is not likely to happen, according to

Teams have 48 hours to complete a deal once a player is claimed off waivers.

The Cubs would like to add an elite starting pitcher to their staff since they dealt right-hander Jeff Samardzija to the Oakland A's. However, the Cubs reportedly prefer to add pitching via free agency so they do not have to give up top prospects while paying for a huge salary.

Hamels has more than four years left on his six-year, $144 million contract. He is 6-6 with a 2.42 ERA this season. He has 139 strikeouts and 40 walks in 137 1/3 innings.

The Phillies are seeking top prospects in exchange for Hamels.

Chicago is expected to go after pitchers Max Scherzer and Jon Lester, who will be free agents this winter.

Philadelphia recently traded right-hander Roberto Hernandez to the Los Angeles Dodgers for two players to be named later after he was claimed off waivers.

Phillies closer Jonathan Papelbon recently cleared waivers. Speculation is that his $13 million salary over the next two seasons scared teams off.
